Randomized Controlled Trial
Vasopressin and methylprednisolone and hemodynamics after in-hospital cardiac arrest - A post hoc analysis of the VAM-IHCA trial.
The Vasopressin and Methylprednisolone for In-Hospital Cardiac Arrest (VAM-IHCA) trial demonstrated a significant improvement in return of spontaneous circulation (ROSC) with no clear effect on long-term outcomes. The objective of the current manuscript was to evaluate the hemodynamic effects of intra-cardiac arrest vasopressin and methylprednisolone during the first 24 hours after ROSC. ⋯ Treatment with vasopressin and methylprednisolone during cardiac arrest caused no difference in mean arterial blood pressure, vasopressor use, or arterial blood gases within the first 24 hours after ROSC when compared to placebo.

Randomized Controlled Trial
Efficacy of Emergency Department Calcium Administration in Cardiac Arrest: A 9-year Retrospective Evaluation.
The efficacy of empiric calcium for patients with undifferentiated cardiac arrest has come under increased scrutiny, including a randomized controlled trial that was stopped early due to a trend towards harm with calcium administration. However, small sample sizes and non-significant findings have hindered precise effect estimates. In this analysis we evaluate the association of calcium administration with survival in a large retrospective cohort of patients with cardiac arrest treated in the emergency department (ED). ⋯ Calcium administration as part of ED-directed treatment for cardiac arrest was associated with lower survival to hospital admission. Given the lack of statistically significant outcomes from smaller, more methodologically robust evaluations on this topic, we believe these findings have an important role to serve in confirming previous results and allowing for more precise effect estimates. Our data adds to the growing body evidence against the empiric use of calcium in cardiac arrest.

Multicenter Study
The Association of Arterial Blood Pressure Waveform-Derived Area Duty Cycle with Intra-arrest Hemodynamics and Cardiac Arrest Outcomes.
Develop a novel, physiology-based measurement of duty cycle (Arterial Blood Pressure-Area Duty Cycle [ABP-ADC]) and evaluate the association of ABP-ADC with intra-arrest hemodynamics and patient outcomes. ⋯ In this multicenter cohort, a lower ABP-ADC was associated with higher sBPs during CPR. Although ABP-ADC was not associated with outcomes, further studies are needed to define the interactions between CPR mechanics and intra arrest patient physiology.

Multicenter Study Observational Study
Annual patterns in the outcomes and post-arrest care for pediatric out-of-hospital cardiac arrest: a nationwide multicenter prospective registry in Japan.
Out-of-hospital cardiac arrest (OHCA) has a poor prognosis in children; however, the annual patterns of prognosis and treatment have not been fully investigated. ⋯ Despite an increase in the rate of bystander-initiated CPR and pre-hospital adrenaline administration, there was no significant change in one-month survival.
